Abstract

A protection unit includes: a protection member including a metal; and a protection film attached to the protection member. A length of the protection member in a first direction is greater than a length of the protection film in the first direction, and the protection film has grooves at respective edges.

Claims (18)

1 . A protection unit comprising: a protection member comprising a metal; and a protection film attached to a first surface of the protection member, wherein a length of the protection member in a first direction is greater than a length of the protection film in the first direction, wherein the protection film has grooves at respective edges, wherein a first side of the protection film in a second direction perpendicular to the first direction overlaps with the protection member, and a second side of the protection film opposite to the first side in the second direction does not overlap with the protection member, wherein no part of the protection member extends farther than the second side of the protection film in the second direction, wherein the grooves of the protection film are located at the first side of the protection film, wherein the protection member has a first side in the second direction adjacent to the first side of the protection film, and a second side opposite the first side in the second direction that overlaps with the protection film, wherein the protection member has grooves that are recessed in the first side and in the first surface of the protection member and that are adjacent to opposite edges of the protection member, wherein the grooves of the protection film are located between the grooves of the protection member along the first direction, and wherein the grooves of the protection member are recessed farther toward the second side of the protection member than the grooves of the protection film.

2 . The protection unit of claim 1 , wherein the grooves of the protection film overlap with the protection member.

3 . The protection unit of claim 1 , wherein the protection film comprises an insulating material.

4 . The protection unit of claim 1 , wherein the protection film is a lamination of an insulation film and a conductive film.

5 . The protection unit of claim 1 , wherein the protection member has a bar shape having the length in the first direction that is greater than a length in the second direction.

6 . The protection unit of claim 1 , wherein at least one of the grooves of the protection film have a polygonal shape.

7 . The protection unit of claim 1 , wherein at least one of the grooves of the protection film have a curved shape.

8 . A protection unit comprising: a protection member comprising a metal; and a protection film attached to a first surface of the protection member, wherein: a length of the protection member in a first direction is greater than a length of the protection film in the first direction; the protection member has grooves at respective adjacent to opposite edges; the protection film has at least one groove; the at least one groove of the protection film is between the grooves of the protection member along the first direction; a first side of the protection film in a second direction perpendicular to the first direction overlaps with the protection member, and a second side of the protection film opposite to the first side in the second direction does not overlap with the protection member; and no part of the protection member extends farther than the second side of the protection film in the second direction, wherein the at least one groove of the protection film is located at the first side of the protection film, wherein the protection member has a first side in the second direction adjacent to the first side of the protection film, and a second side opposite the first side in the second direction that overlaps with the protective film, wherein the grooves of the protection member are recessed in the first side and the first surface of the protection member, and wherein the grooves of the protection member are recessed farther toward the second side of the protection member than the grooves of the protection film.

9 . A display device comprising: a display panel comprising a display area and a non-display area; a driver at the non-display area; and a protection unit on the driver at the non-display area, and not overlapping with the display area, wherein the protection unit comprises: a protection member overlapping with the driver, and a protection film attached to a first surface of the protection member, wherein a length of the protection member in a first direction is greater than a length of the protection film in the first direction, wherein the protection film has at least one groove, an entirety of the at least one groove overlapping with the protection member to expose a part of the protection member, wherein the protection member has a first side in a second direction, perpendicular to the first direction, adjacent to the first side of the protection film, and a second side opposite the first side in the second direction that overlaps with the protection film, and wherein the protection member has grooves that are recessed in the first side and in the first surface of the protection member, wherein the at least one groove of the protection film is located between the grooves of the protection member along the first direction, and wherein the grooves of the protection member are recessed farther toward the second side of the protection member than the at least one groove of the protection film.

10 . The display device of claim 9 , wherein the protection film has a plurality of grooves at respective edges of the protection film.

11 . The display device of claim 9 , wherein: the protection member has the grooves at respective edges.

12 . The display device of claim 9 , wherein the driver overlaps with the protection film and the protection member.

13 . The display device of claim 9 , wherein the protection film comprises an insulating material.

14 . The display device of claim 9 , wherein the protection film is a lamination of an insulation film and a conductive film.

15 . The display device of claim 9 , wherein the protection unit has a bar shape having a length in the first direction that is greater than a length in a second direction perpendicular to the first direction.

16 . The display device of claim 9 , wherein the at least one groove has a polygonal shape or a curved shape.

17 . The display device of claim 10 , wherein shapes of the plurality of grooves of the protection film are different from each other.

18 . The display device of claim 9 , wherein the protection member comprises a metal.
